Which outcome accelerates coastal erosion when streams carrying sediment are dammed?

💡 Explanation

Reduced sediment supplied to the coast occurs because sediment trapping behind the dam prevents depositional equilibrium; therefore, wave action erodes beaches and cliffs rather than replenishing them, causing increased coastal erosion, rather than bluff stabilizations.
